Calycanthine is the principal alkaloid of the family Calycanthaceae. Calycanthine is a central nervous system toxin, causing convulsions in animals. Calycanthine may mediate its convulsant action predominantly by inhibiting the release of the inhibitory neurotransmitter GABA as a result of interactions with L-type Ca(2+) channels and by inhibiting GABA-mediated chloride currents at GABA(A) receptors.
